Ah jla #4.. that's good I thought I was going mad as I have read and own all of mark waids flash in comic and trade format including morrisson and millar's short run and the flash geoff john' 0mnibus's... I've been meaning to get round to purchasing and reading morrissons whole jla run in trade and this has piqued my interest
Morrisons jla run.. is it as good as I have heard?
Never heard any complaints in regard to Gmo's JLA run. I think its the one thing that even Morrison haters could get in to.
In Alan Davis' JLA: The Nail, Superman and a Krypton-Grafted Jimmy Olsen were hitting eachother so hard it created devestating shockwaves. So any Kryptonian on Kryptonian fight will yield some major damage even outside of the actual fight.
One of my favorites:

Superman(in bizarro's body) hit bizarro(in clark's body) so hard that he ended up on the other end of the earth in china.
Hawkman hitting Superman with the weight of the entire Earth behind his punch was the first thing that came to mind (from Superman/Batman #4 (2004)):
Batman: I need your help finding a man named Vulko.
Hawkman: You want him dead or alive?
- Justice League #17
Nowhere near the hardest no doubt but i immediately thought of this:
Major Force punched superman across a couple of state from metropolis to Ohio and KO him.
